Solar Cell Scribing Machine
A photovoltaic cell (commonly called a solar cell) is a nonmechanical device usually made from silicon alloys. It converts sunlight into electricity. The PV cell was discovered in 1954 by Bell Telephone researchers. Late 1950s, PV cells were used to power U.S. space satellites.Individual cells can vary in size from about 1 cm (1/2 inch) to about 10 cm (4 inches). Most photovoltaic cells are about ten percent efficient in covering sunlight to electricity with further research being conducted to raise this efficiency to fifteen-twenty percent.Photovoltaic conversion is useful for several reasons. Conversion from sunlight to electricity is direct, so that bulky mechanical generator systems are unnecessary. The modular characteristic of photovoltaic energy allows arrays to be installed quickly and in any size required or allowed.Presently BCSC (Buried Contact Solar Cells) and Polycrystalline CdTe-baser Photovoltaic are the latest technology in the solar cells and having efficiency is around 15-20 % approx. and we can get stable power output and long life. HOW DOES A SOLAR CELL WORK? Sunlight is composed of photons, or particles of solar energy. These photons contain various amounts of energy corresponding to the different wavelengths of the solar spectrum. When photons strike a photovoltaic cell, they may be reflected, pass right through, or be absorbed. Only the absorbed photons provide energy to generate electricity. When enough sunlight (energy) is absorbed by the material (semiconductor), electrons are dislodged from the material's atoms. Special treatment of the material surface during manufacturing makes the front surface of the cell more receptive to free electrons, so the electrons naturally migrate to the surface. When the electrons leave their position, holes are formed. When many electrons, each carrying a negative charge, travel toward the front surface of the cell, the resulting imbalance of charge between the cell's front and back surface creates a voltage potential like the negative and positive terminals of a battery. When the two surfaces are connected through an external load, electricity flows. WHAT IS SCRIBING AND WHY SCRIBING IS NECESSARY? Scribing means, cutting of a grid pattern of grooves in a semiconductor material generally for the purpose of marking interconnections or to cut the solar cells into two parts.Laser scribing is done for the fabrication of monolithic cell interconnections. Scribing, either with a mechanical stylus or a laser is used for fabricating series interconnections allowing a large, thin-film photovoltaic panels to be made with, for example, 100 cells monolithically interconnected. The series interconnection allows the same electrical power to be produces from the panel with a voltage 100 times that of an individual cell and the current equal to that of one cell. For CdTe thin films, the individual cell voltage is about 0.8V

Laser Marking System
PERMANENT Laser marking is permanent and indelible marking process, which stands against wiping, scuffing, impacts, wear and tear, can only be removed by grinding or surface removal. Thus laser - marking sustains authenticity of your brand against sort of tempering NON-CONTACT TYPE Laser marking is non-contact type process. It does not produce any deformation in product unlike in punching, stamping, pneumatic pin, vibratory pencil etc. This gives accurate and aesthetic marking independent of hardness of material. FLEXIBILITY Laser marking is highly flexible process compared to any other marking process. It can mark any images and fonts without changing any punch, die, stencil etc. unlike other conventional process. AESTHETIC/ACCURACY Since laser can produce very fine beam with accuracy in micron, many accurate and micro details with precision can be marked with laser marking. Laser can produce aesthetic images which otherwise difficult to create with other marking process. NO PRE/POST PROCESSING Since Laser marking is non-contact type, no pre or post processing is required, which in turn significantly increase marking productivity. LOW OPERATING COST Laser marking helps significantly in cutting operating cost by reducing labor cost, tool cost, consumable cost, set up time, rejection improved cycle time. AUTOMATION One of the prime advantage of laser marking is that it can be automized and can be integrated with any online process. With support of software, even variable serial nos., batch nos., date of bar code can be marked.
